When Chicago Mayor Rahm Emanuel accepted Iowa Democrats’ invitation to be the featured guest at their big annual fundraiser this fall, the theory that he might be hot for the presidency immediately began to circulate.

“[He’s the] President of the United States. I’ve done two trips already at the request of the … president’s re-election campaign. They’ve asked me to be a surrogate. I’ll do it. [But] I’m not interested [in running for President]. I love this job. I love the people of the city of Chicago. I love working on behalf of the taxpayers. Not interested.”

Asked if 2016 was in his sights, Emanuel said no, according to the Sun-Times.

Traditionally the Democrats’ biggest bash in Iowa, the landmark dinner attracts thousands of party leaders and activists for food, speeches, receptions – and a fundraiser that hauls in serious money. It’s also a chance for Democrats to tout their message and build team spirit.

And it’s a place where up-and-comers can test their presidential aspirations.
